LOUIS IIORVATH, OF LOS ANGELES, OALIFORNIA.

SPECIFICATION forming part of Letters Patent No. 679,383, dated July 30, 1901.

l Application filed March 28, 1901. Serial No. 53,328. (No model.)

.T all whom it may concern:

Be it known that I, LoUIs HoRvATH, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful linprovements in Lawn-Sprinklers, of which the following is a specification.

My invention relates to rotary lawn-sprinklers; and the object thereof is to produce a sprinkler which may be attached directly to the hydrant, and thereby dispense with the use of hose. I accomplish this object by the device described herein and illustrated in the accompanying drawings, forming apart hereof, in which- Figure lis a view of my sprinkler attached to a hydrant. Figs. 2 and 3 are detail views in section to show the construction of the joints of my sprinkler.

In my lawn-sprinkler described in the patent issued to me December 4, 1900, No. 663,277, I achieved very fine results; but with that device the water is discharged in one direction until its course is changed by the operator.

The object of my present invention is to produce a sprinkler' that will automatically revolve and distribute water over almost as large a space as can be covered by my former sprinkler.

In the drawings, A is the hydrant, to which is coupled the U-shaped body B, the outer leg B of which is longerV than the inner one. The inner leg is coupled to the hydrant, so that the portions of the sprinkler which revolve may not contact with the hydrant. To the outer leg is attached the quadrant elbow 0 by its base 0', to which is screwed collar 0, the bore of which is slightly less than that of the base and through which passes the reduced portion of the coupling-tube 0'", which screws into the body 0"" and holds the parts of the elbow from separating, as the lower portion of the coupling-tube is too large to pass through the collar. Quadrant elbow 0 is formed of the base 0, collar 0, tube 0"', and curved body 0, with the other end screw-threaded in the manner usual to elbows. Surrounding the coupling-tube is a ring E, of packing, which when the collar is firmly screwed on the base forms a water-tightjoint the couplingand at the same time permits tube and body to revolve. To the quadrant elbow 0 is attached the quadrant elbow D, of the same construction as that of elbow 0, eX-

cept that the coupling-tube is shorter, the

base is somewhatshorter, and the lower part of the bore of the base is less than the eX- terior diameter of the lower part of the coupling-tube. This change is made for the purpose of partly unscrewing the base from the collar and then turning the body of the elbow to any desired position and holding it in such position by screwing the base and collar together; as illustrated in Fig. 2. To elbow D is attached the nozzle G, adapted to throw a stream or spray, which completes my sprin kier.

vWhen it is desired to prevent the rotation of the sprinkler, I provide thumb-screw F, mounted on collar 0", which may be screwed against body 0" to prevent its turning.

The short leg of the body B may be of any suitable shape for attaching it to the hydrant; but all curves in the sprinkler should `be arcs of a circle and the curves of the body and the elbows should be of the same radius to produce the best results.

In the operation of my sprinkler elbow D is set at'such an angle as will give the water the desired spread, andthe force of the water causes body 0, elbow D, and the nozzle to rotate.

I-Iaving described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. Asprinkler comprising a U -shaped body having one leg thereof longer than the other, the curves of which are arcs of a circle, a quadrant elbow-shaped member, composed of a base, adapted to be screwed upon the longer leg of the body; a collaradapted to be screwed upon the base; a curved body; a coupling-tube having one end thereof reduced in size and adapted to pass through the collar and screw into the curved body; a second quadrant elbow adapted to be screwed upon. the first elbow also composed of a base; a collar; a coupling-tube and a curved body, the enlarged portion of the coupling-tube being adapted to be caught and held against rotation by the base and collar when in their operative position, and a nozzle, all constructed and operated as described herein.
